AGRICULTURAL MACHINE.

To all whom it may concern:

Be it known that I, Fnnonurcx SIEMANN,

a citizen of the United States, residing at Fort Lupton, in the county of \Veld and State of Colorado, have invented certain new and useful Improvements in Agricultural Machines, of which the following is a specification. My invention relates to improvements in agricultural machines, and refers particularly to a riding attachment for carders or barrows.

The leading object of the invention is to provide a riding attachment for land carders and barrows which may be mounted directly upon the equalizer bar of the machine, thereby adding the weightot the operator to inure its steady and smooth operation and a constant depth of out for the ground working tools.

An important object of the invention is to provide a simple and durable connection between the axle of the machine and the frame whereby the operator may regulate the depth of out.

A further object of the invention is to provide a novel form of connecting arm or rod for connecting the axle and the frame, said arm having a locking connection with the frame when the axle is fastened to the arm or rod.

Other objects of the invention are to provide a riding attachment for barrows or land carders whichwill be capable of use upon the machines of the present type now used; which'attachment will be exceedingly simple and durable in construction; and which will be highly ellicient and practical.

With the attainment of these and other objects in view, my invention broadly stated consists in the provision of a seat mounted upon the equalizer bar of the frame, arms connecting the axle with the teeth or tool carrying frame, and chains connecting the equalizer-bar, axle and connecting arms. the invention further residing in certain novel features of construction and combinations of parts for service, substantially as disclosed herein. Figure l is a top plan view of a land carder constructed in accordance with and embodying the principles of my invention. Fig. 2 is a side elevation of the sa'me. Fig. 3 is a vertical sectional view on line 3'3 of Fig. 1. Fig. 4 is a detail view of a hook and eyedevice used'to connect the arms and Specification of Letters Patent.

carder frame. Fig. 5 is a detail view, partly in section, of one of the connecting arms or rods. Fig. 6 is a sectional view. on an enlarged scale, taken on line 6-4.3 of Fig. 5;. and Fig. 7 is a perspective view of the shoe detached from the frame.

In the drawings :--the numeral 1 desire notes the axle, 2 the ground wheels, 3 the equalizer bar, 4 the side bars, 5 the inclined bars, 6 the tongue, 7 the inclined brace rods, and 8 the ground working tools of an ordinary land carder, the tongue and forward part of the frame bars being secured toether by means of the transversely extendlng bolts 9 and the tongue having the customary clevis 10, provided with a draft connection 11 for moving the cardcr through the field, a shoe 12 depending from the forward portion of the tongue and having a suitable brace 13, the shoe or runner per-initting transportation.

The numeral 14 designates the operators seat, supported from the equalizer bar by the inclined supports 15, secured at 16 thereto,

to the tongue. A

The axle is connected to the frame by means of the curved arms 19, formed at their rear ends with the eyes 20, which engage over the axle and are retained in place by the pins '21. passing through openings in the axle and having their ends bent as atv :23 to engage around thieyes of the arms. The arms are each provided with lugs 24 adapted to engage the links of the chains 25, passing over the axle and arms and connected to the equalizer bar. The forward extremities of the arms terminate in eyes 26, through which pass and are secured by means of cotter pins 27, the extensions 28 of the books 529. formed with eyes 30. through which pass bolts 31 for securing one end of the braces T; a ground working tool 8, and one end of the inclined bars 5 of the frame together.

From the foregoing it will be seen that the links of the chains engage the lugs on the arms to regulate the depth of cut of the ground working tools to a predetermined level and that tl e'o ierator can by reason of the peculiar connections between the axle and equalizer bar cause the ground working tools to hear more firmly into the ground. The depth of cut is detern'iined by the length l of the chains 25 as compared with the radius t of the ground wheels 2, the connection betit) and by the central support 17, secured at 18 t-ions foisned with eyes ta-ween the iaxle and frame at all times reteiningg' the rem? end of the frame substantially zii predetermined level, lgutpermitting the trout end of the frame to assume various and varying levels v ueritorious feature of the invention resides in the construction and connection 'of the forward ends of the arms 19 to the 351'; ne the bolts 31 being utilized to both s'ecure the grouni'l Woi'l ing tools and the frame hails upon each other as well to'i'etain thh forward ends of the arms in place.

il hile I have shown and described my improve of C01 he understood that I do not limit myself to any particular type ofagriculturel machine, but reserve the rightto use the invention in any capacity Where it would pe'forn'i its functions in. a thoroughly efiicicnt and practical manner. Nor do I Wish to limit myself to the precise details of construction herein shown and described, but may make such variations and modifies-- as full clearly within the spirit and scope of the invention, as circumstances rcqui lit will be understood that in Fig. 2 the shoe or runner is shown in the position it occupios when my machine is in condition to he teensported or drawn from. place to place that when itis desired to use the n'ischins in the performance of its funclions the shoe or runner is removed, allowing the teeth 01 tools to he free to enter the ground I cluiin:-
